GATE.

SPEGIFIGATION forming part of Letters Patent No. 471,851, dated March29, 1892. Application filed November 27, 1891. Serial No. 413,300. (Nomodel.) 7

To all whom it may concern:

Be it known that I, JOSEPH ELCOCK, a citizen of the United States,residing at Mechanicsburg, in the county ,of Cumberland and State ofPennsylvania, have invented new and useful Improvements in Gates, ofwhich the following is a specification.

This invention relates to improvements in that class of gates thatarearranged to slide on and between rollers that are supported by thegate-posts; and it consists in the construction and combination of partsin a sliding gate, as hereinafter more fully described, and particularlypointed out in the claims.

In the annexed drawings, illustrating the invention,Figure 1 is aperspective of myimproved sliding gate, showing the same as it appearswhen open. Fig. 2 is a vertical crosssection through the line 2 2 ofFig. 1, showing the vertically-adjustable roller-bearing box I forraising and lowering the end of the gate to give it a proper set. Fig. 3is a vertical cross-section through the line 3 3 of Fig. 1, showing moreclearly the grooved chain-wheel or double pulley and its crank-shaft foract-uating the gate. Fig.4 is aview of a modified arrangement of devicesfor revolving the pulley-shaft. Fig. 5 is a detail view of aportion ofthe forward end of a gate, showing the gatestile extended upward andcarrying a roller to run on a rail or cross-bar connecting theupwardly-extending ends of two gate-posts.

Referring to the drawings in detail,'the numeral 1 designates the gateproper, which is composed of the usual stiles and longitudinal bars thatmay be suitably braced in any convenient manner, as shown.

The numeral 2 designates the latch-post, which is provided with verticalflanges 3 on the side toward the adjacent end of the gate, thus forminga vertically-elongated recess 4, into which one of the gate-stilesenters when the gate is closed. At the foot of this recess 4 is ananti-friction roller 5, that facilitates engagement of the gate with thelatch-post.

The main gate-post 6 is made double or composed of two standards havingtheir inner faces provided with vertical guideways 7 for receiving avertically-elongated and vertically-adjustable box 8, in the oppositeends of which are journaled the flanged guide-rollers 9, between whichthe gate 1 is mounted, and along which the upper and lower longitudinalbars of the gate are enabled to slide freely and easily in opening andclosing the gate. On the top of the double post or twin standards 6 issecured a plate or cross-piece 10, having a central screw-threadedaperture for passage of a screw-threaded crank-shaft 11, that is looselyconnected with the upper end of the vertically-ad j ustable box 8, 1nwhich the rollers 9 are mounted. By turning the screw-shaft 11 in theproper direction the rollers 9 can thus be raised or lowered, asrequired, for the purpose of impartingthe desired set to the gate, so asto enable 1t to be operated with ease. I

At one side of the gate 1,between the latchpost 2 and main post 6, isarranged an lntermediate post 12, to which is secured a bracket 18, inthe upper and lower ends of which are journaled flanged guide-rollers 14above and below the upper and lower longitudinal gatebars, respectively,to assist in supporting and guiding the gate. The post 12 and bracket 13also support a rotary shaft 15, on WhlCll, between said post andbracket, is securely mounted a double-grooved wheel or pulley 16 forattachment of chains or ropes 17, that are extended to the opposite endsof the gate'and secured thereto in any suitable manner. The attachmentof these ropes or chains 17 to the opposite ends of the gate maybeeifected either by means of screw-eyes 18 oreyebolts 19, as preferred,or by any other convement means. The grooved wheel or pulley 16 may berotated by means of a crank-handle 21 on the pulley-shaft 15, as shown.in Fig. 3, or, as

shown in Fig. 4, the crank may be replaced by a double-grooved wheel 22,having attached thereto ropes 23,passed over pulleys 24 at the top ofthe post 12 and carrying welghts 25 at their free ends, so that bypulling down on one of said ropes it will be unwound from the wheel 22while the other weighted rope 23 1s wound thereon. By means of theseweighted ropes 23 and grooved wheel 22, or by means of the crank 21, asthe case may be, the shaft 15 and double-grooved wheel 16 may be rotatedin the desired direction to open or close the gate. When the gate ismoved in elther direction, as above described, one of the chains 17 willbe unwound from the grooved wheel 16 as the other chain is wound thereonby the turning of the wheel and its shaft.

As shown in Fig. 5, the gate-posts 2 and 12 may be extended upward andconnected by a rail or cross-bar 26 to support a roller 27 on theupward-extended end of the forward gatestile, thereby furtherfacilitating the opening and closing of a heavy gate. The rail orcrossbar 26 should be supported at a sufficient height to permit thepassage of vehicles.

It will be seen that the described arrangement of the sliding gate andits operating mechanism is such as to enable the gate to be readilyopened and closed without the exertion of any great amountof strength orpower, owing to the smoothness with which it will move in its bearingsor supports. When closed, the gate is firmly and staunchly supported,and when open it exposes almost the entire width of the roadway for thepassage of vehicles.

What I claim as my invention is 1. The combination, with a latch-post 2,a main gate post 6, comprising two parallel standards having guidewaysat their inner sides, and an intermediate post 12, having upper andlower guide-rollers 14, of averticallysliding roller-box 8, engaged withthe guideways of the standards and provided with upper and lowerguide-rollers 9, a cap-plate 10, connecting the upper ends of thestandards and having a screw-threaded orifice, and a rotatingscrew-shaft 11, engaging the threaded part of the cap-plate, providedwith a crankhandle, and loosely connected with the upper end of theroller-box, substantially as described.

2. The combination, with a latch-post 2, a main gate post 6, comprisingtwo parallel standards having guideways at their inner sides, a slidinggate 1, and an intermediate post 12, having upper and lowerguide-rollers 14, and a rotating grooved wheel provided with a ropewound thereupon and connected with opposite ends of the gate, ofaverticallysliding roller-box S, engaged with the guideways on the maingate-post and provided with upper and lower guide-rollers 9, a cap-plate10, secured to the main gate-post and having a screw-threaded orifice,and a rotating screwshaft 11, engaging thethreaded part of thecap-plate, provided with. a crank-handle, and loosely connected with theupper end of the roller-box, substantially as and for the purposesdescribed.

In testimony whereof I have hereunto set my hand and affixed my seal inpresence of two subscribing witnesses.
